Is it actually possible? Has it been possible in the past? Did this option ever get discussed? Did google ever talk about it?
If not possible, one can't actually upload (or repost) a CC-BY-SA video on YouTube because being only CC-BY publishing available, that would constitute a copyright violation, am I right?
So, I can't upload on YouTube an original work derived from a CC-BY-SA publisher like Wikipedia, am I right?
